I started out playing golf seven years ago with what is termed a vertical grip (or "weak" grip in non-G.O.L.F. terms) and my wrist always felt weak and vulnerable to injury because of many mishits. So basically I changed to a strong grip (I believe what I do would be more like 10-2-D) because of that and due to poor quality of impact (ball contact).

The 10-2-B Grip may not be as weak as you think.

Do this again: Extend your Left Arm straight in front of yourself, parallel to the ground with fingers extended, you will end up looking like 4-C-1. Now keeping your Left Wrist Vertical and your Left Arm parallel to the ground, swing the whole of your Left Arm about six inches to your right (just like a door). Without changing anything from this position, drop your Left Arm into a golf-like like position. Important: Note how your Left Wrist seems to be slightly Turned! In fact, it's perfectly Vertical! It's Vertical to the Horizontal Plane.

Another point. Following directly from above, keeping the same alignments, place a club into the heel pad of your left hand. If you did everything correctly, your fingers should still be extended. Now if you wrap your fingers around the grip, notice how the Left Wrist looks very slightly more turned!

Yet another point. If you place your left thumb slightly to the right of centre of grip as per last paragraph of 10-2-0 ("aft"), as you wrap your fingers around the grip, your left wrist will look more turned than if you placed your left thumb in the convential centre line position.

Hope this helps Mike!
